SOAP MANUFACTURING PROCESS:

The plant is usually divided into Three Sections.
1. Pan Boiling Section/Crutcher Saponification Section.
2. Vacuum Drying Plant.
3. Toilet Soap Processing Line

STORAGE OF MATERIALS :
Vegetable oils/Animal Fats are stored into storage tanks with steam heating coils.
The material may be received into tank lorries or druLD of 200 litres. To facilitate the
unloading of oils from the druLD, underground steel tank (rectangular) needs to be
fabricated at site. Three oil storage tanks (cLDindrical, vertical) needs to be fabricated at
site for storing different oils viz. Palm Fatty Acids, Animal Tallow, Coconut oil etc.
Similarly Separate storage tanks for Caustic Soda Liquid and Sodium Silicate solution are
fabricated. If Caustic Soda is received at Factory in solid state, caustic melting tank (5-10
KL) capacity is also fabricated at site to dissolve solid caustic soda into liquid form
(47%). Sodium silicate mixing tank is fabricated at site to dissolve salt in Sodium silicate
to make it fluid for pumping.

Different oils are mixed in oil blending vessel in fixed proportions as per finished product
formulation is required and pumped to overhead storage tank in the Pan Boiling Section.
Caustic Soda liquid is directly pumped to the overhead soda tank. Water is received in
water overhead tank directly from the water source (tubewell etc.)

PAN BOILING : This section is set up in plants where very dark coloured oils are
proposed to be used in the process. Oil is charged into the soap boiling pans and heated
with open steam coils (Three nos. provided) and simultaneous caustic soda and water
addition is done to maintain the moisture, alkali ration in the boiling soap. The soap
boiling operation (for 10 MT oil charge) takes about 4-5 hours for completion. The pans
to be fabricated at site should have a volumetric capacity of 3-3.5 times of the oil charge
taken. At the end of boiling operation, salt is added to split the soap from glycerin lye
(spent lye) to separate out in layers. Lower layer of spent lye is discarded to lye treatment
section for waste disposal OR the spent lye is used in Glycerin Recovery Plant.

The soap from first boiling change is further washed with open steam,
water and small amount of caustic soda liquid to complete the saponification (above
99%). At the end of second boiling operation, the soap is again split with salt to separate
soap spent lye (called Half spent lye as it contains lesser glycerin). The half-spent lye is
transferred to empty pan to be utilized with fresh oil charge in place of water. The soap
remaining is finally boiled with steam, water to complete the FITTING operation. In this
case the soap is not split but homogenized to form the neat soap (containing 62%TFM)
and Niger (30-32% TFM). The neat soap is transferred to Vacuum Drying Plant for
making Laundry Soaps or Toilet Soap Noodles. The Niger is recycled to first boiling
change with fresh oils.

CRUTCHER SAPONIFICATION : In case the raw materials consist of fatty acids, the
soap is made in crutcher saponification process and PAN BOILING stage is avoided.
The fatty acid mixture made as per guidelines above as oils and taken into soap crutcher.

Water and caustic soda in liquid form are added in stoichiometric proportions so that all the

oils and fatty acids are neutralized fully and free caustic alkali present in the final mass of soap

is not above 0.05%. Some salt water (upto 1%) is added to remove stickiness of the

soap mass. The final TFM of the soap mass is adjusted at 50-52%. This soap is

used as neat soap in the vacuum drying plant for producing soap noodles for

toilet soap manufacturing.

If Laundry Soap/Carbolic soap is to be produced, other chemicals lLD colour, minor
chemicals etc are also added into the crutcher.

The neat soap from pan boiling section is received in the soap crutcher. Minor chemicals

lLD Titanium Dioxide, colour, preservatives are added and mixed in the crutcher. The
coloured soap from the crutcher is passed through the soap filter to remove any oversize

particles and stored in Feed vessel for spraying. The soap from feed soap is sprayed into

the Vacuum Dryer by variable speed feed pump by passing through heat exchanger. In the
vacuum spray chamber flash drying of soap takes place under high vacuum and finished
soap with desired moisture content is allowed to pass to the duplex vacuum plodder
placed underneath the Vacuum Chamber. The exhaust air is highly humidified and
contains some fine particles of soap. These fine particles of soap are recovered into the
powder separation group and moist air is sucked by Vacuum ejector and condensed into
the barometric condenser placed at +32ft heigLD. The barometric condenser is connected
to Water ring Vacuum pump through air-water separator to create the desired vacuum in
the plant.
The laundry soap is extruded in the form of bars from the final plodder of the duplex
vacuum plodder. Perfuming is done at the intersection of the duplex vacuum plodder
without applying vacuum in the interconnection. The continuous soap bars coming out
from final duplex plodder are cut into 4-5 cake length soap bars by continuous rotary bar
cutter. A brand name embossing is done on the roller itself or the brand name can be
embossed on individual Cake Cutting Machine as desired. The final soap cakes are
packed into polybags/paper wrapper as per market requirement.

SOAP PROCESSING LINE:
Soap noodles obtained from above process is stored in storage silo. Noodles are weighed
in a batch size for sigma batch mixing operation. The soap noodles are mixed
homogeneously into the sigma mixer with other ingredients lLD colour, specialty
chemicals, perfume etc.
The mixed soap noodles are dropped into the receiving hopper of Refining Plodder where
the soap is extruded into fine noodle shapes by giving further refining effect to soap mass
and partially changing the soap structure.

The refined soap is passed through Triple Roll Mill to further homogenize the soap mass
to impart shine and lustre to soap. The soap film is conveyed by means of a conveyor to
the top plodder of Duplex Vacuum Plodder. The top plodder further refines the soap and
gives steady continuous feed of soap to bottom extruding plodder. The intersection of two
parts of this plodder is vacuum-sealed to remove any traces of air remaining in the soap
mass, so that the final extruded soap is compact in structure.
The final plodder extrudes the soap into continuous bar shape. The bars (4-5 cake length)
are cut automatically by rotary bar cutter and further cut into small cake as per weigLD
and size requirement of the soap by means of a cake cutting machine.
The cut pieces of soap are passed on to soap stamping machine which presses the soap to
give shape and size along with brand name stamping on the finished soap. The stamped
soap is further packed into paper/plastic wrapper or into colour printed cartons by manual
operation or by a packing machine.
